iptables: execvp: ERROR

[Natasha69]

Ok...i have my own iptables script trying to get it going...here what i have soo far in it...just starting
SPECS:
RedHat 7.2
2.4.19 Kernel
iptables-1.2.3

#######################################
#!/bin/bash

echo 1 = > /proc/sys/net/ipv4//ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

# Remove any existing rules from all chains.
iptables --flush
iptables -t nat --flush

# Unlimited access on the loopback interface
iptables -A INPUT -i lo -j ACCEPT
iptables -A OUPUT -o lo -j ACCPET

# Set the fefault policy to Drop
iptables --policy INPUT DROP
#######################################
Now... to get this to run on start-up here is what i did but it didnt start up it gave me an error.
chown root.root /etc/init.d/firewall
chmod u=rwx /etc/init.d /firewall

And when i restart i get an error... which is
[gloworange]"iptables: execvp: Permission Denied
rc. Starting iptables: Failed"[/gloworange]
I also have this line sh /etc/init.d/firewall at the end of my "rc.local" file
How can i fix this??? Or get them to start up propeply!!!

EDIT: > OOPPPPPPSS guys i forgot to mention the original iptables script that came installed already on my system in the "/etc/init.d/" i moved that to somewhere else.... was i suppose to do that or just leave them there???

Hello...

Just thought i would tell anyone if they ever get this problem starting up their firewall script the future I fixed it by :

chown root:root /etc/init.d/firewall and
chmod 775 /etc/init.d/firewall
and this, but not sure if this helped or not...

chmod u=rwx /etc/init.d /firewall
